What medications should not be taken after a Contrast CT Scan?
There are no generally contraindicated medications after a contrast enhanced Ct Scan.
Your Ignition coil on primary resistance reading 0.0 ohms repair manual states it should be approx 1.0 ohms is it shorted?
Depending on the accuracy of your Ohm meter, yes... it could very well be shorted.
Can I have a CT scan of my heart with metal rods in my back?
CT uses x-Rays. There should be no problem at all.
Do I have to take out a genital piercing for an abdominal CT scan?
That's something you should check with your doctor about and definitely ask the CT technician.
Should a woman who has had breast cancer have a CT scan?
If the CT was recommended by a doctor, you should probably have it. if it is simply because you want to know whether it is completely gone, talk to your doctor, who can then recommend the scan as above.
Why potential transformers are open circuited?
Beacause CT is shorted so it is kept opened
Can you saturate a CT with the secondarys shorted?
A CT becomes saturated when the induced secondary voltage is beyond the capabilities of the CT. Yes it is possible, if enough current is forced through the secondary to raise the voltage beyond the CT capability curve. Remember the CT has inherent resistance due to the secondary winding. That said, to saturate strictly based on the CT resistance is unlikely. But it is still theoretically possible.
Preparation for a ct scan abdomen?
should you eat before having a ct scan of the chest and abdomen

Why must a fuse or Switch never be fitted to the secondary of a CT circuit?
Secondary of a CT should never be opened to avoid damage to CT. Fuse or switch may lead to opening of CT secondary accidentally.

Depending on the accuracy of your Ohm meter, yes... it could very well be shorted.
Why can a CT be shorted and a Pt cannot?
A current transformer pushes a ratio of primary current in the secondary. A potential transformer pushes a ratio of primary voltage in the secondary. Shorting a CT allows the full current the CT wants to push to flow. Shorting a PT makes it very difficult for the PT to produce rated voltage. To keep the voltage at rated value, the PT would have to push ~infinite secondary current.
How to know if the resistor is open and shorted?
I assume that the person asking the question meant "open OR shorted" as these are opposite terms. Most resistors will open when they are damaged. It is very rare to find one that is shorted. To determine if the resistor is open or shorted simply use a multimeter set to measure ohms. Place the leads across the resistor and it should read the resistance value of the resistor. If it measures max range of the meter (some digitals will display "OL") then the resistor is open. If it measures 0 or very close then it is shorted, which as mentioned above, is unlikely.
What could be the cause if meter M3 displays a higher current reading than it should?
resistor R1 is shorted

What is a current transformer and how can a current transformer be used to extend the range of a wattmeter?
A current transformer (CT) works just like any other transformer. It is important to note it is not referenced to ground. It reflects current flow, not phase to ground voltage, so it attempts to hold current constant, not voltage. There is usually one primary "winding": one large cable through a donut CT, and multiple secondary windings. If a secondary winding is shorted (a wire placed across its terminals), the voltage built up in the secondary will be equivalent to V = I*Z, where I is the secondary current, and Z is the impedance of the secondary winding, usually specified as some flat value plus so many ohms per winding. If too big of an impedance is placed on the secondary, a voltage will build up to the point that the donut CT saturates, resulting in an output wave that has a large amount of harmonics. If the CT is open circuit\'d, voltage will build up until it is high enough to arc over (usually where it should have been shorted). CT\'s can be damaged by open circuiting them, so don\'t do it.
